EM-18 TTL RFID reader Module: The EM-18 module is commonly used in projects for RFID (Radio Frequency Identification) readers. It enables direct interface with microcontrollers through UART communication. This particular module is specifically designed to read codes from 125 KHz card compatible read-only tags and also allows for read/write capabilities. Each card is identified by a unique value stored in the chip inside. Highlighted characteristics of EM-18 TTL RFID reader Module: Frequency used: 125Khz The baud rate is set at 9600. The interface options available are TTL or Wiegand26. The voltage needed for operation is between DC 3.3V and 5V. Current usage: 19mA to 25mA. The maximum reading distance is 35mm. The operating temperature ranges from -10℃ to 70℃. Temperature range for storage: -20℃ to 80℃ The humidity level ranges from 0% to 95%. Output in both Serial and TTL formats. Superb read capabilities without the need for an external circuit. Small and budget-friendly. Incorporating an RFID coil antenna. Efficient energy usage Inexpensive Steps to establish a connection: Attach a 5V power supply to the RFID TTL connection. Upon connecting the power supply, the LED will blink. Connect the Tx pin of the EM-18 module to the TTL Rx. The coil within the EM-18 module produces emf pulses for card detection purposes. The card is equipped with both a coil and a chip that houses a distinctive hexadecimal code, which is then sent through the TTL transmitter. The buzzer will sound upon reading the card. The expected result will be in the form of a hexadecimal value and can be found in an external terminal, such as a PC. There are various ways in which this software can be utilized.
